Based on a survey of 9512 ninth-grade students conducted in Lower Saxony in 2013, this paper examines the prevalence of cyberbullying perpetration and the correlates of this behavior. Binary logistic multilevel regression was used in order to analyze correlates of sexual and psychological cyberbully perpetration. In the preceding semester, 2.4% of the adolescents were perpetrators of psychological cyberbullying and 0.4% bullied someone online sexually. Low levels of empathy, frequent consumption of violent media, and being victims of aggressive online behaviors are correlated with the risk that a child will become a bully. Female adolescents are less likely than boys to engage in sexual cyberbullying perpetration, but they are more likely to engage in psychological cyberbullying perpetration. Only a small share of adolescents engage in sexual and psychological cyberbullying perpetration. Both behaviors differ in their correlates, however being a victim of aggressive online behaviors increase the risk for perpetration of both behaviors, respectively.

Experience of bullying may be a significant risk factor for non-suicidal self-injury (NSSI). This study had three aims: to systematically investigate the association between bullying and NSSI, analyze the possible mechanisms underlying the two phenomena, and evaluate any differences between bullying victimization and bullying perpetration with respect to NSSI. A systematic search about the association between bullying victimization and perpetration and NSSI was conducted using specific databases (PubMed, Scopus, Science Direct). The following keywords were used in all database searches: \"bullying\" AND \"NSSI\" OR \"peer victimization\" and NSSI. The searches in PubMed, Scopus and Science Direct revealed a total of 88 articles about bullying or peer victimization and NSSI. However, only 29 met our inclusion criteria and were used for the present review. Overall, all studies examined victimization; four studies also evaluated the effects of perpetration and one included bully-victims. According to the main findings, both being a victim of bullying and perpetrating bullying may increase the risk of adverse psychological outcomes in terms of NSSI and suicidality in the short and the long run. To the best of our knowledge, this is the first review to systematically evaluate the relation between bullying victimization/perpetration and NSSI. The main results support a positive association. Future research should evaluate the possible role of specific mediators/moderators of the association between experience of bullying and NSSI.

Twenty-three samples from 22 longitudinal studies assessing both bullying perpetration and bullying victimization were selected from a sample of 1,408 candidate studies using several prespecified criteria (i.e., participants ≤ 18 years of age; self-reported bullying victimization and perpetration assessed with a lag of at least 1 month but no more than 24 months; not a treatment or program study). A random effects meta-analysis was then performed on the concurrent and cross-lagged longitudinal associations between bullying victimization and perpetration in the 23 samples. A large pooled effect size (r = .40, 95% confidence interval [CI] = [.34, .45]) was obtained for the concurrent association between bullying victimization and perpetration, whereas modest to moderate effect sizes (victimization to perpetration: r = .20, 95% CI [.17, .24]; perpetration to victimization: r = .21, 95% CI [.17, .24]) were obtained for the two cross-lagged longitudinal correlations. The results did not change when analyses were conducted separately for traditional bullying and cyberbullying outcomes. These findings indicate that bullying victimization and perpetration correlate strongly and that their cross-lagged longitudinal relationship runs in both directions, such that perpetration is just as likely to lead to future victimization as victimization is to lead to future perpetration. Different theoretical models are proposed in an effort to explain these results: cycle of violence, general strain, and social cognitive theories for victimization leading to perpetration and risky lifestyles, routine activities, and peer selection theories for perpetration leading to victimization.

Background: The prevalence of sexual perpetration in college men is unknown. Prior reviews of sexual violence prevalence rates have produced wide-ranging estimates, likely due to wide variation in measurement strategies. Objectives: This article systematically reviewed research findings (from 2000 to 2017) regarding prevalence rates of sexual perpetration in college men and measurement strategies. Data Sources: PsycINFO and Web of Science databases. Eligibility Criteria: Empirical reports published between 2000 and 2017 that included male participants, available in English, and reported lifetime prevalence findings in Canadian or American college students. Participants: Data from 78 independent samples including 25,524 college men. Results: The average prevalence rate of any sexual perpetration was 29.3% (SD = 16.8), and the average rate of rape was 6.5% (SD = 6.3). Studies that used non-Sexual Experiences Survey (SES)–based questionnaires recorded higher prevalence rates (41.5%) than SES-using studies (26.2%). At least 16 different sexual perpetration questionnaires were identified. Modifying standardized questionnaires was extremely common; this was reported in over half of the studies. Studies using modified standardized questionnaires found higher prevalence rates of sexual perpetration than studies using nonmodified standardized questionnaires. Limitations: This report focused exclusively on college men in the United States and Canada. Conclusions and Implications: On average, 29% of college males report engaging in behaviors defined as sexual perpetration; however, there was a strong influence of measurement strategy on reported rates.

Objective: The attachment theory is a useful framework for interpreting the phenomenon of intimate partner violence (IPV) perpetration. Although several studies have examined the relationship between attachment and IPV perpetration, a meta-analysis of these results has yet to be conducted. Method: After a search on five databases (PsycINFO, PsycARTICLES, MEDLINE, Scopus, Web of Science, and PubMed) and a screening of 3,852 records recruited, 52 studies comprising 13,653 individuals met the inclusion criteria for this meta-analysis. Results: Results showed a significant effect size for both the anxiety and avoidance dimensions of attachment. However, while the effect sizes for anxiety were consistent (r = .19–.35) for all types of violence considered, the effect size for avoidance was not significant for generic violence (r = .07), low for physical (r = .12) and psychological violence (r = .14), and medium for sexual violence (r = .20). Only a few of the examined moderators were significant. Conclusions: The findings highlight some differences in the roles of the two attachment dimensions in IPV. The results underscore the need for additional research to explore the role of other potential moderating and mediating variables in the relationship between attachment and IPV perpetration in order to better support the development of prevention and treatment interventions.

(1) Background: Co-occurrence or overlaps of different forms or involvement in peer violence among adolescents have been broadly studied. The study aimed to assess adolescents’ violence profiles related to bullying, cyberbullying, and fighting in the Czech Republic, Hungary, Poland, and Slovakia. The study was to investigate the pattern of bullying, cyberbullying, and fighting involvement among adolescents in these four countries to test the stability of previously identified profiles. (2) Methods: We analyzed the data from the 2017/2018 international Health Behaviour in School-aged Children survey, which used proportionate sampling among adolescents aged 11–15 years old (n = 24,501). A Latent Class Analysis (LCA) was performed to determine violence profiles in each country. (3) Results: In Slovakia, three distinct latent classes were identified, primarily cyber victims, school bullies, and those involved in multiple forms, and in the Czech Republic, Hungary and Poland bully victims was the fourth class. (4) Conclusions: The findings suggest that peer violence prevention programs in adolescents should consider violence profiles and multiple involvements.
